One number to rule them all: The Wildlife Sperm Index for standardized gamete assessment

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract In wildlife conservation, breeding programmes focused on reintroduction are critical to recovering endangered species. Assisted reproductive technologies (ARTs) and biobanking play pivotal roles in these efforts but depend on high‐quality gametes.

The Ticking Clock: Differential Time‐Dependent Deterioration Between Washed and Thawed Sperm

open access: yesAndrology, EarlyView.
ABSTRACT Background Cryopreservation is widely used in assisted reproductive technologies. While fresh sperm undergoes gradual time‐dependent deterioration, it remains unclear whether thawed sperm exhibits a more accelerated decline. Objectives To directly compare the rate of deterioration in sperm motility, vitality, and DNA fragmentation between ...

Identification and Quantification of Volatile Organic Compounds and Bioaerosols in the Conservation Processes of Guanche Mummies

open access: yesArchaeometry, EarlyView.
ABSTRACT The Guanche mummies, ancient inhabitants of the Canary Islands, represent a significant part of the historical heritage preserved at the Museum of Nature and Archaeology (MUNA) in Tenerife, Spain. These mummies, subjected to artificial conservation practices, are of great interest to conservators seeking to understand their mummification ...

Compartmentalisation in cAMP signalling: A phase separation perspective

open access: yesBritish Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no
